Good point. Makefiles also fall into that category, I wonder
what other languages are whitespace sensitive?

It's usable for 99% of patches for the kernel, though. But
right, dfpost:$BLOB_ID matches should take precedence, and we
can use a lower weight for the patch-id in Xapian
The bigger question is the cost in time to reindex...
And ultimately, I wonder if dfpost:$BLOB_ID + s:$COMMIT_TITLE
is good enough, too... I think I need to dig out something
I abandoned years ago for indexing coderepos and refactor that
to be less space-intensive now.
